To all whom it may azmcern Be it known that L Ci-LARK V. Mofinnnnr, a citizen of the United States, and a resident of McGlure, in the county of Henry and State of @hio, have invented anew and useful Light Deflector, which invention is fully set forth in the following specification.

My invention has for its object to provide an eflicient light deflector for confining the rays of light from the headlight of an automobile to the road, and preventing the rays of light from entering the eye of the driver of an approaching automobile. A great variety of light deflectors have here t'ofore been used but on account of diffusion of light from the reflector of the lamp, it has been practically impossible by the use of the deflectors heretofore known, to confine the rays of light to the road and prevent them from blinding the driver of an approaching automobile.

By my invention is provided a reticulated member having a plurality of deflectors covering the openings of the member to confinethe rays of light that pass through the openings to a particular directigm, and thus preventing the dilfused rays irom ris ing to a height hQ h oadway? which would otherwise cause the blinding of the driver of an approaching vehicle. The member may be used in coniunction with a VlSOI'. It may be constructed so as to cover the entire lens of the lamp, or to cover only the lower or a part of the lens of the lamp. Preferably, it is constructed to COW/r t e lower alf. the Mrs 9 li ht passing ough th ppe hal being diverted by means of a visor e i v n i n may h ehta n d i stru u e which in hei detail vh y- T lnetrate a practical application of the inven; t hn, I h ve se e d stru ture sust ni the n i n a d shall descr e it he -elaafter. The deyice embodying the invention is illustrated in the accompanying drawings.

Figure 1 is a front view of an automobile lamp, having a visor and a perforated mem her having parts to deflect the light that passes through the openings of the member.

Figure 2 is a side view of the device partly in section.

The lamp 1 is provided with the usual lens confining ring 2 that is usually secured to the lamp by a'bayonet slot connection in the manner well known in the art, It is men ee s rh t d to se u e he 99301 glass 3 between a flange or inwardly extending ledge 4 formed on the body of the lamp and a ledge or flange 5 formed onthe rim; These two parts press against opposite sides of the glass 3 to support the glass 3 in position. l

The rays of light that are reflected from the upper half of the reflector would always theoretically be refleoted'to the road at a point determined by the focusing of the light. but owing to the diffusion the ay of e'ht o e h an ev ry W lli 0 the deflector from which the reflected light a at s me of th ht t strik s th upper half of the reflector does not follow the focused rays. but distributes itself'upd y as ell as d w wa dly: T e 1-wwardly extending rays enter the eye of the driver of a distant vehicle and on account of the difference of the light and darkness at night he is blinded by the rays that are thus diffused. To prevent such rays enteri s he @3 Of n apr a hina river he visor 6 is used. The visor -.6 extends forward some distance in advance of the lamp so as to completely intercept the diffused upwardlv directed rays of light. It, however, so

shaped at its forward edge as to permit the focused rays to extend in proper theoretical paths or lin s to light the roadway. The visor is formed of sheet metal and is shaped to conform with substantially one-half of a frhs m f a a e s det r ne a pl n p sina h ou t ar of th rhstum, The isor 6 is m n ed i ange 7 whe y h isor *6 may h s re n resit an j if 9 h am by h sh mmer rin 2.- Th o ward edge 8 f e i er ub t n ly con rm to a e mi ir le and the Radius of the semis-circle described by he flange 7 lot t e v so .6 i ccas demhly greater than the radius of the circle described by the forward edge 8 of the visor. Furthermore, the forward edge of the visor is located slightly above the center of the rays of light so as to avoid interception of the properly focusing rays of light and yet sufficiently low to prevent the rays of light coming directly from the lamp to rise high enough to enter the eye of the driver of an approaching vehicle. Furthermore, the visor is of sufficient length to intercept
